CONDUCTOR STRAlNER.

SPECIFICATION forming part of Letters Patent No. 380,873, dated April 10, 1888.

Application filed February 25, 1888. Serial No. 265,295. (No model.)

To all whom it may concern:

Be it known that I, PAUL DRENDUL, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Conductor-Strainers, of which the following is a specification.

My invention relates to conductor strainers or guards which are most commonly inserted in the top ends of rain-water conductors or leaders, was to prevent the entrance into the conductor or leader of leaves and other refuse which would be liable to clog it. Such a conductor-strainer is composed of a series of ribs extending upward and downward and usually of wire, and these ribs are united and held at regular distances apart by horizontal binders of wire. The ribs usually converge to a ring at the upper end of the strainer, to which ring their ends are attached by bending the wire of the ribs around said ring. Usually two horizontal binders are employed, one being at the top of the strainer and the other being some distance below the top and usually midway of the length.'

In such strainers as heretofore constructed the binder has usually consisted of a ring of comparatively heavy wire-sucl1 as that of which the ribs are formed-and a fine lacingwire which is entwined around the wire of said ring and coiled around each rib.

The object of my invention is to provide a binder which will be stronger than the one heretofore used and above described,and which will also be more easily and with less labor combined with the ribs.

My invention therefore consists in a condoctor-strainer composed of ribs extending upward and downward and having a horizontal binder composed of two rings of crimped wire laid one on another, and having the ribs inserted in the holes formed by the crimps or bends of the two rings which are opposite each other, the wire of one ring lying outside alternate ribs and inside the intermediate ribs and the wire of the other ring lying inside such alternate ribs and outside such intermediate ribs.

In the accompanying drawings, Figure 1 is an elevation of a strainer embodying my invention including, also, a section of the upper part of a conductor or leader to which the strainer is applied; and Fig. 2 is a plan of the strainer.

Similar letters of reference designate corresponding parts in both figures.

A designates the leader or conductor, into the upper end of which the strainer is inserted. The strainer is composed of a series of ribs, B, extending substantially upward and downward, save at their upper portions, which are curved outward and thence inward, converging to a common center at the top of the strainer. mately the form shown in Fig. l. The several ribs B, which may be made of wire, are at their upper ends secured to a ring, I), by bending the ends of the ribs about such a ring, as is best shown in Fig.2. Certain of the ribs, however, which are opposite each other in the strainer may be formed of. a single piece of wire and extend directly across the central ring, I), and in thepresent example of my invention two wires,formin g four ribs, thus cross the center of the strainer. i

In order to hold the ribs B at the desired distance apart and prevent them from being displaced, so as to come nearer to each other at some part of the circumference of the strainer, and to spread at some other part, so as to allow refuse to enter between them, I provide lateral binders B, which serve to hold the ribs at the desired distance apart. I have here shown the strainer as having two such binders, one being at the top, where the ribs B converge inward, and the other being below the swelled portion of the strainer. This latter binder forms, as here represented, a stop for limiting the depth to which the strainer is inserted into the conductor or leader A. Each of the binders B B is formed of two rings, 1), of crimped wire-that is to say, wire which has short transverse bends throughout its length, or which is of zigzag form around the circumference of the ring. These two rings 12 are laid one on another and the ribs B are inserted through the holes b formed between the crimps or bends which are opposite each other in the two rings. The wire I) of one ring lies outside alternate ribs and inside the intermediate ribs, and the wire of the other This gives the strainer approxt.

ring D lies inside such alternate ribs and outside such intermediate ribs. The two rings 1) which form each binder are of wires which are substantially equal in size, and may be combined with the ribs much easier than when the binder is composed of a ring of comparatively heavy wire and a light lacing-wire, and a binder formed according to my invention is much stronger than one formed in the old way and the ribs are not displaced orbent out of shape when applying the binder.

What I claim as my invention, and desire to secure by Letters Patent, is-

The conductor strainer herein described, composed of ribs extending upward and downward and a horizontal binder composed of two rings of crimped wire laid one on another, and having the ribs inserted in the holes formed by the crimps or bends of the two rings which are opposite each other, the wire of one ring lying outside alternate ribs and inside the intermediate ribs, and the wire of the other ring lying inside such alternate ribs and outside such intermediate ribs, substantially as herein described.

PAUL DRENDUL.
